Review ITM ENGINE COMPONENTS Piston Pin Bushing Toyota Cressida fits SUPRA CROWN 1968–1992

The **ITM Engine RB4008 Piston Pin Bushing** is a precision-engineered aftermarket replacement part designed specifically for Toyota s legendary **20R, 22R, and 24R inline-six engines**, found in iconic models such as the **1968 1992 Toyota Supra, Cressida, and Crown**. Crafted from high-quality **oil-impregnated bronze**, this bushing serves as a critical wear component that supports the **piston pin (wrist pin)**, ensuring smooth articulation between the piston and connecting rod while minimizing friction and heat buildup. The RB4008 model is meticulously machined to exacting tolerances, matching the original equipment specifications to prevent binding, excessive wear, or catastrophic failure common issues in high-mileage or performance-oriented engines. Its robust construction resists deformation under heavy loads, making it an ideal upgrade for both stock applications and modified setups, including those with forced induction or aggressive camshafts. Whether restoring a classic Supra to its original glory or pushing a Crown s engine to new limits, this bushing delivers reliable performance, reducing the risk of piston pin slop, rod bearing damage, or costly internal engine wear. Backed by ITM s reputation for durability and compatibility, this part is a straightforward yet essential solution for maintaining the structural integrity of Toyota s legendary inline-six engines across their entire production span.

### **Pros and Cons of Buying ITM Engine RB4008 Piston Pin Bushing (1968 1992 Toyota Supra/Cressida/Crown)**

#### **Pros:**

1. **Direct Fitment** The ITM piston pin bushings are specifically designed for the Toyota RB4008 engine, ensuring compatibility with the 1968 1992 Supra, Cressida, and Crown models. This eliminates the need for modifications or conversions, reducing installation complexity.

2. **Improved Durability** The bushings are made from high-quality materials, often reinforced with steel or other wear-resistant alloys, which can extend the lifespan of the piston pins compared to stock components. This is particularly useful in high-performance or heavily modified engines where wear is accelerated.

3. **Reduced Friction and Wear** Properly fitted bushings reduce friction between the piston pin and the piston, which can lower internal engine wear and improve efficiency. This may contribute to smoother operation and potentially better fuel economy in some cases.

4. **Easy Installation** ITM parts are known for straightforward installation procedures. The kit typically includes clear instructions, and the components are designed to fit without extensive machining or special tools, making it accessible for DIY enthusiasts.

5. **Support for Performance Upgrades** If you re running a turbocharged, forced-induction, or high-RPM setup, these bushings can help mitigate stress on the piston pins, which are critical components under heavy loads. They may also be part of a broader rebuild or upgrade package.

6. **Reliability from a Trusted Brand** ITM (International Truck Parts) is a well-regarded aftermarket brand with a reputation for quality and reliability in engine components. Their products are widely used in the Toyota RB engine community, offering peace of mind for buyers.

7. **Cost-Effective Replacement** While not the cheapest option, these bushings are often more affordable than a full engine rebuild or replacement. They represent a targeted upgrade to address a specific wear point without overhauling the entire engine.

#### **Cons:**

1. **Cost** Compared to OEM (original equipment manufacturer) parts, aftermarket bushings like ITM s are typically more expensive. For a complete set, the price can range from $50 to $150 or more, depending on the source and whether additional components (like seals or pins) are included.

2. **Potential for Overkill** If your engine is in excellent condition with minimal wear, upgrading the piston pin bushings may not be immediately necessary. These bushings are a preventive or performance-focused upgrade rather than a strictly necessary repair.

3. **Installation Skill Required** While ITM parts are designed for ease of use, improper installation such as incorrect lubrication, misalignment, or overtightening can lead to premature failure or damage to other engine components. This requires careful attention to detail.

4. **Compatibility Considerations** While ITM bushings are designed for the RB4008, there may be slight variations depending on the specific year or engine variant (e.g., early vs. late RB40s). Double-checking the fitment details for your exact model is crucial to avoid issues.

5. **Limited Longevity in Extreme Conditions** In highly aggressive driving conditions (e.g., extreme high-RPM racing, excessive turbo boost, or frequent hard acceleration), even high-quality bushings may wear out faster than stock components. This could require more frequent replacements.

6. **Availability and Lead Times** Like many aftermarket parts, ITM piston pin bushings may not always be in stock at local shops. Purchasing online might involve waiting for shipping, which could delay your project timeline.

7. **Potential for Counterfeit Parts** Buying from untrusted sellers (especially online marketplaces) carries a risk of receiving counterfeit or low-quality imitations. Always purchase from reputable dealers or authorized ITM distributors to ensure authenticity.

### **Conclusion**

The ITM piston pin bushings for the RB4008 engine are a **high-quality, performance-oriented upgrade** that offers tangible benefits for enthusiasts looking to extend engine life, reduce wear, or support high-performance modifications. They strike a balance between durability and ease of installation, making them a practical choice for those who prioritize reliability and longevity.

However, they are **not a necessity for every RB4008 owner**. If your engine is running smoothly with no signs of pin or bushing wear, the cost and effort may not justify the upgrade. On the other hand, if you re planning a rebuild, a performance project, or notice excessive play in your piston pins, these bushings are a **wise investment** to prevent catastrophic failure and improve overall engine health.

For most **high-mileage, modified, or heavily used RB4008 engines**, upgrading to ITM bushings is **highly recommended**. For **stock or lightly used engines**, they may be optional unless you re anticipating future modifications or want extra peace of mind.

---

### **Final Recommendation**

- **Buy the ITM piston pin bushings if:**

- You re rebuilding or overhauling your RB4008 engine.

- You notice excessive piston pin wear or play.

- You re running a turbocharged or high-performance setup.

- You want to future-proof your engine against premature wear.

- **Avoid or delay purchasing if:**

- Your engine is in pristine condition with no signs of wear.

- You re on a tight budget and other engine components are more critical to address first.

- You re unsure about installation skills and lack access to proper tools or guidance.

**Purchase from an authorized ITM dealer or a trusted aftermarket supplier** to ensure quality and authenticity. Always follow the installation instructions carefully to maximize the lifespan of the bushings and the engine.
